3A are the beams, which maybe of any desired length, and may have anydesired `number of ploughs attached to them. `The'forward-ends vofthebeamsA meet and are pivoted to each other by the shankor standard of thei l forward plough, which passes up'through holes formed intheends ofstrapsa, attachcdto theends ofthe said bea-ms Af.
